Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, and particularly relates to a combined activated carbon adsorber. Background Technique

[0002] Due to its porous structure and large specific surface area, activated carbon has strong adsorption capacity, so it is widely used in waste gas treatment, mainly for adsorbing and removing impurities from gases in industrial production, and then discharging them into the air after removing harmful substances to avoid polluting the atmosphere.

[0003] The current combined activated carbon adsorber ingeniously adopts the strategy of paralleling multiple adsorption beds to significantly improve the treatment capacity and efficiency. When waste gas enters, it will be guided into multiple parallel channels, each of which is equipped with an activated carbon layer, so as to ensure that the waste gas can fully contact the activated carbon and be effectively purified. A significant advantage of this modular design is that when one or some adsorption beds approach or reach the adsorption saturation point of the activated carbon due to long-term use, they can be maintained or replaced separately without interrupting the operation of the entire system;

[0004] However, although this design brings many conveniences, there is also a key problem to be solved: due to the differences in operating conditions of each adsorption bed in actual operation (such as uneven distribution of waste gas flow, differences in activated carbon performance, etc.), the adsorption saturation rates of the activated carbon in each group of adsorption beds are different. Once one or several groups of activated carbon reach the saturation state first, if not identified and replaced in time, these saturated activated carbon will lose their purification ability, resulting in the ineffective separation of impurities in the waste gas, and then may be directly discharged into the environment with the waste gas, causing pollution;

[0005] Since it is difficult to know the adsorption state of each group of adsorption beds, when the staff finds that the purification efficiency of the system has decreased, they often need to first interrupt the input of waste gas, and then open the activated carbon adsorber to check one by one to determine which adsorption beds need to replace the activated carbon. Opening the activated carbon adsorber and checking the adsorption state of each group of adsorption beds one by one is a time-consuming and labor-intensive task, which not only increases the labor cost, but also may lead to inaccurate or missed inspections due to human factors, and is very time-consuming. Content of the Utility Model

[0006] The purpose of the utility model is to provide a combined activated carbon adsorber to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, a combinable activated carbon adsorber provided by the utility model includes an adsorber housing and an adsorption bed housing, including a pallet placed inside the adsorption bed housing, two tripods installed at the bottom of the pallet, a slide bar disposed on one side of the tripod, with its outer wall abutted against the tripod, two springs installed at the bottom of the pallet, a lead screw, one end of which is connected to one end of the slide bar and the other end extends outside the adsorption bed housing, and the lead screw is slidably connected to the adsorption bed housing, two rotating shafts, one end of each of which is rotatably connected to the adsorption bed housing, and a transmission belt is drivingly connected between the two rotating shafts, one of the rotating shafts is threadedly connected to the lead screw, a belt is disposed above the pallet, and a plurality of air inlet holes are provided in the belt, a fixing frame is installed on the top of the transmission belt, with its outer wall connected to the outer wall of the belt, and an air inlet groove is opened on one side of the adsorption bed housing and corresponds to the belt.

[0008] Further, a chute is opened in the adsorption bed housing, and the belt is located inside the chute and is slidably connected to the chute.

[0009] Further, a transmission wheel is installed on the outer wall of the rotating shaft, and the transmission belt is drivingly connected between the two transmission wheels.

[0010] Further, a sleeve is installed on the inner wall of the adsorption bed housing, and one end of the slide bar is located inside the sleeve and is slidably connected to the sleeve.

[0011] Further, a plurality of push-button switches are installed on the inner wall of the sleeve, and a plurality of lights electrically connected to the push-button switches are installed on the outer wall of the adsorption bed housing.

[0012] Further, two support plates are installed on the inner wall of the adsorption bed housing, the springs are installed on the top of the support plates, a support rod is connected between the two support plates, a through groove is opened in the slide bar, and the support rod is slidably connected to the through groove.

[0013] Further, a slot is opened in the adsorption bed housing, the rotating shaft is located inside the slot and is rotatably connected to the slot, the transmission wheel is located outside the adsorption bed housing, and the pallet is used to support the activated carbon.

[0014] Further, a plurality of balls are rotatably connected to the bottom of the belt, a slideway is opened in the adsorption bed housing, the slideway is located below the air inlet groove, and the balls are slidably connected to the inner bottom wall of the slideway.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In the present utility model, as the activated carbon adsorbs impurities and gains weight, the supporting plate gradually presses down the spring, driving the sliding rod and the lead screw to move. The lead screw drives the rotating shaft to rotate, and the transmission belt drives the fixed frame and the belt to move, causing the air inlet holes to gradually move out of the air inlet groove. When all the air inlet holes leave the air inlet groove, it indicates that the activated carbon is saturated. At this time, the air inlet groove is also blocked by the belt, preventing the waste gas from entering further.

[0017] 2. In the present utility model, as the sliding rod slowly slides into the sleeve, it presses four push-button switches in sequence. Each push-button switch controls a lamp correspondingly. The number of lit lamps directly reflects the adsorption state of the activated carbon: the more lamps are lit, the heavier the activated carbon is, and the more impurities it adsorbs. When all the lamps are lit simultaneously, it indicates that the activated carbon has reached the adsorption saturation, and the staff can directly replace the activated carbon in the outer shell of the adsorption bed.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0030] Refer to Figures 1-8 As shown, a combinable activated carbon adsorber includes an adsorber housing 1 and an adsorption bed housing 2, including a tray 3 placed inside the adsorption bed housing 2, two tripods 13 fixedly installed at the bottom of the tray 3, a sliding rod 17 arranged on one side of the tripod 13, whose outer wall abuts against the tripod 13, two springs 14 fixedly installed at the bottom of the tray 3, a lead screw 6, one end of which is fixedly connected to one end of the sliding rod 17, and the other end extends to the outside of the adsorption bed housing 2, and the lead screw 6 is slidably connected to the adsorption bed housing 2, two rotating shafts 11, one end of each of which is rotatably connected to the adsorption bed housing 2, and a transmission belt 10 is drivingly connected between the two rotating shafts 11, one of the rotating shafts 11 is threadedly connected to the lead screw 6, a belt 5 is arranged above the tray 3, and the belt 5 is provided with a plurality of air inlet holes 8, a fixing frame 12 is fixedly installed at the top of the transmission belt 10, whose outer wall is fixedly connected to the outer wall of the belt 5, and an air inlet groove 7 is opened on one side of the adsorption bed housing 2 and corresponds to the belt 5.

[0031] Activated carbon is placed on the top of the tray 3. The spring 14 is used to support the tray 3 and the activated carbon. A specific spring 14 is selected so that the tray 3 will not immediately press down the spring 14 to cause the spring 14 to contract after the activated carbon is placed on the tray 3. Since the activated carbon will gradually become heavier after adsorbing impurities, as the weight of the activated carbon increases, the tray 3 will gradually squeeze the spring 14, causing the spring 14 to slowly contract;

[0032] After the tray 3 moves downward, the tripod 13 will squeeze the sliding rod 17, so that one end of the sliding rod 17 squeezes the lead screw 6 and makes the lead screw 6 move towards the outside of the adsorption bed housing 2. The lead screw 6 will not rotate itself when moving, so one of the rotating shafts 11 threadedly connected to the lead screw 6 will rotate, and the rotation of the rotating shaft 11 drives the other rotating shaft 11 to rotate through the transmission belt 10, realizing the rotation of the transmission belt 10 between the two rotating shafts 11;

[0033] When the transmission belt 10 moves, it drives the fixed frame 12 to move, and the fixed frame 12 drives the belt 5 to move. When the multiple air inlet holes 8 are located in the air inlet groove 7, the exhaust gas entering the adsorber housing 1 will enter the air inlet hole 8 through the air inlet groove 7, and then enter the adsorption bed housing 2 through the air inlet hole 8, and float to the activated carbon on the top of the support plate 3;

[0034] When the fixed frame 12 drives the belt 5 to move, the air inlet hole 8 will gradually move away from the air inlet groove 7. When all the air inlet holes 8 are away from the air inlet groove 7, the belt 5 will block the air inlet groove 7. At this time, the exhaust gas can no longer enter the adsorption bed shell 2 through the air inlet groove 7 and the air inlet hole 8. When all the air inlet holes 8 are pushed away from the air inlet groove 7, it means that the weight of the activated carbon in the support plate 3 has reached the saturated level of activated carbon adsorption. At this time, closing the air inlet groove 7 can prevent the exhaust gas from being discharged through the saturated activated carbon.

[0035] See also Figure 3 The adsorption bed shell 2 is provided with a slide groove 4, the belt 5 is located inside the slide groove 4 and is slidably connected to the slide groove 4, and the outer wall of the belt 5 is in contact with the inner wall of the slide groove 4.

[0036] The slide groove 4 provides space for the belt 5 to move and enables the belt 5 to be stable in the slide groove 4. At the same time, the belt 5 fits closely with the slide groove 4 to prevent the exhaust gas from entering the adsorption bed shell 2 through the gap between the belt 5 and the slide groove 4.

[0037] See also Figure 3 A transmission wheel 21 is fixedly mounted on the outer wall of the rotating shaft 11 , and the transmission belt 10 is connected between the two transmission wheels 21 .

[0038] The transmission wheel 21 makes the transmission belt 10 taut, so that when one of the rotating shafts 11 and the transmission wheel 21 rotates, the other transmission wheel 21 and the rotating shaft 11 can be quickly driven to rotate through the transmission belt 10, and the transmission wheel 21 can prevent the transmission belt 10 from deviating or slipping during the transmission process, thereby ensuring the stability and reliability of the transmission.

[0039] See also Figures 4-5 A sleeve 18 is fixedly installed on the inner wall of the adsorption bed shell 2 , and one end of the sliding rod 17 is located inside the sleeve 18 and is slidably connected to the sleeve 18 .

[0040] The sleeve 18 can support the slide bar 17 so that the slide bar 17 can slide along the sleeve 18 when encountering resistance.

[0041] See also Figure 3 and Figure 5 A plurality of button switches 20 are fixedly mounted on the inner wall of the sleeve 18 , and a plurality of lamps 9 electrically connected to the button switches 20 are fixedly mounted on the outer wall of the adsorption bed shell 2 .

[0042] The four push-button switches 20 respectively correspond to the four lights 9. As the sliding rod 17 slowly slides into the sleeve 18, the sliding rod 17 will gradually press the push-button switch 20. The number of push-button switches 20 pressed represents the number of lights 9 that light up;

[0043] The staff can determine the adsorption situation of the activated carbon inside the adsorption bed housing 2 by observing how many lights 9 are lit on the different adsorption bed housings 2. The more lights 9 that are lit, the heavier the activated carbon and the more impurities it adsorbs. If all four lights 9 are lit, it means that the weight of the activated carbon has reached its peak and the activated carbon is saturated with adsorption. At this time, the staff does not need to conduct a check and can directly remove the adsorption bed housing 2 with all lights 9 lit and replace the activated carbon.

[0044] Refer to Figure 4 and Figure 7 On the inner wall of the adsorption bed housing 2, two support plates 15 are fixedly installed. The spring 14 is fixedly installed on the top of the support plate 15. A support rod 19 is fixedly connected between the two support plates 15. The sliding rod 17 is provided with a through groove 23, and the support rod 19 is slidably connected to the through groove 23.

[0045] The support plate 15 supports the spring 14, and the support plate 15 is located between the two tripod supports 13. Therefore, when the tripod support 13 moves downward, it will not touch the support plate 15. The support rod 19 supports the sliding rod 17. When the sliding rod 17 is squeezed by the tripod support 13, the sliding rod 17 can slide along the outer wall of the support rod 19 through the through groove 23, making the sliding rod 17 more stable and less likely to deviate.

[0046] Refer to Figure 8 The adsorption bed housing 2 is provided with a slot 16. The rotating shaft 11 is located inside the slot 16 and is rotatably connected to the slot 16. The transmission wheel 21 is located outside the adsorption bed housing 2. The support plate 3 is used to support the activated carbon.

[0047] When the lead screw 6 moves, the rotating shaft 11 will rotate. To prevent the rotating shaft 11 from moving together with the lead screw 6, the rotating shaft 11 is limited by the slot 16. The slot 16 enables the rotating shaft 11 to only rotate along the inside of the slot 16 and cannot leave the inside of the slot 16.

[0048] Refer to Figure 6 At the bottom of the belt 5, a plurality of balls 22 are rotatably connected. The adsorption bed housing 2 is provided with a slideway 24. The slideway 24 is located below the air inlet groove 7. The balls 22 are slidably connected to the inner bottom wall of the slideway 24.

[0049] To make it smoother for the fixing frame 12 to pull the belt 5, a plurality of balls 22 are provided at the bottom of the belt 5. When the belt 5 is pulled, the balls 22 will slide along the inside of the slideway 24, which makes it easier to move the belt 5 and prevents the belt 5 from deforming.

[0050] Working principle:

[0051] Activated carbon is placed on the top of the pallet 3. The spring 14 is used to support the pallet 3 and the activated carbon. A specific spring 14 is selected so that the pallet 3 will not immediately press down the spring 14 to cause the spring 14 to contract after the activated carbon is placed on the pallet 3;

[0052] Since the activated carbon will gradually become heavier after adsorbing impurities, as the weight of the activated carbon increases, the pallet 3 will gradually squeeze the spring 14, causing the spring 14 to slowly contract. Because activated carbon is a porous carbonaceous substance with a large number of micropores and mesopores on its surface, these pore structures endow activated carbon with strong adsorption capacity. When activated carbon is placed in an environment containing impurities such as harmful gases in gas and suspended solids in liquid, these impurity molecules will be adsorbed into the pores of the activated carbon, resulting in an increase in the mass of the activated carbon. Therefore, as the adsorption process progresses, the activated carbon will gradually become heavier;

[0053] In order to prevent the spring 14 from being immediately squeezed before the activated carbon becomes heavier, a spring 14 with appropriate stiffness and pre-tightening force needs to be selected. Specifically, the stiffness of the spring 14, that is, the rate at which the elastic force changes with its compression or stretching, should be large enough to keep the position of the pallet 3 stable under the initial weight of the activated carbon. At the same time, the pre-tightening force of the spring 14, that is, the initial compression amount of the spring 14 when it is not subjected to external forces, needs to be adjusted properly to ensure that the spring 14 will not be compressed before the weight of the activated carbon increases;

[0054] After the pallet 3 moves downward, the tripod 13 will squeeze the sliding rod 17, causing one end of the sliding rod 17 to squeeze the lead screw 6 and making the lead screw 6 move towards the outside of the adsorption bed housing 2. The lead screw 6 will not rotate when it moves, so one of the rotating shafts 11 threadedly connected to the lead screw 6 will rotate;

[0055] The rotation of the rotating shaft 11 drives the rotation of another rotating shaft 11 through the transmission belt 10, realizing the rotation of the transmission belt 10 between the two rotating shafts 11. When the transmission belt 10 moves, it drives the fixed frame 12 to move, and the fixed frame 12 drives the belt 5 to rotate along the inner wall of the chute 4. When multiple air inlet holes 8 are located in the air inlet groove 7, the waste gas entering the adsorption housing 1 will enter the air inlet groove 7 through the air inlet holes 8, then enter the adsorption bed housing 2 through the air inlet holes 8, and float towards the activated carbon on the top of the pallet 3;

[0056] When the fixed frame 12 drives the belt 5 to move, it will gradually drive the air inlet holes 8 into the inside of the chute 4. When all of some air inlet holes 8 enter the chute 4, the part of the belt 5 without air inlet holes 8 will block the air inlet groove 7. At this time, the waste gas can no longer enter the adsorption bed housing 2 through the air inlet groove 7 and the air inlet holes 8. And when all the air inlet holes 8 are pushed away from the air inlet groove 7, it means that the weight of the activated carbon in the pallet 3 has reached the degree of adsorption saturation of the activated carbon. At this time, the air inlet groove 7 is closed to prevent the waste gas from being discharged through the saturated activated carbon.

[0057] Four push-button switches 20 respectively correspond to four lamps 9. As the sliding rod 17 slowly slides into the sleeve 18, the sliding rod 17 will gradually press the push-button switch 20. The number of push-button switches 20 pressed represents the number of lamps 9 that are lit.

[0058] The staff can determine the adsorption situation of the activated carbon inside the adsorption bed housing 2 by observing how many lamps 9 are lit on the different adsorption bed housings 2. The more lamps 9 that are lit, the heavier the activated carbon and the more impurities it has adsorbed. If all four lamps 9 are lit, it means that the weight of the activated carbon has reached its peak and the activated carbon is saturated with adsorption. At this time, the staff does not need to conduct a check and can directly remove the adsorption bed housing 2 with all lamps 9 lit and replace the activated carbon.
